Description

本発明は、空気圧縮機のシリンダ排気構造に関し、特に、シリンダ上に排気ベースが設けられ、排気ベースの外筒壁には、複数の排気孔が形成され、排気ベースの外筒壁には、弾性薄膜が嵌設され、空気圧縮機により発生された圧縮空気が複数の排気孔を介して弾性薄膜を押動し、空気貯蔵ユニットの空気貯蔵チャンバ内に進入し、弾性薄膜が速やかに閉じる特性を利用し、空気貯蔵ユニットの空気貯蔵チャンバ内に進入する単位時間当たりの圧縮空気量を増大させ、圧縮された空気が排気孔を速やかに通って空気貯蔵チャンバ内に進入し、ピストン本体が円滑に動作してポンピング効率が高い、空気圧縮機のシリンダ排気構造に関する。 The present invention relates to a cylinder exhaust structure of an air compressor, in particular, an exhaust base is provided on the cylinder, a plurality of exhaust holes are formed in the outer cylinder wall of the exhaust base, and the outer cylinder wall of the exhaust base has a plurality of exhaust holes. A characteristic in which an elastic thin film is fitted, compressed air generated by an air compressor pushes the elastic thin film through a plurality of exhaust holes, enters the air storage chamber of the air storage unit, and the elastic thin film closes quickly. Increases the amount of compressed air per unit time that enters the air storage chamber of the air storage unit, and the compressed air quickly passes through the exhaust holes and enters the air storage chamber, smoothing the piston body. Regarding the cylinder exhaust structure of an air compressor, which operates in a high pumping efficiency.

従来の空気圧縮機の構造は、基本的にシリンダを含む。シリンダ内でピストン本体が往復運動すると、圧縮空気が発生する。発生した圧縮空気がシリンダの排気孔を介してバルブ機構を押動し、圧縮空気を貯蔵するもう一つの空間に圧縮空気が進入する。この空間は、例えば、空気貯蔵ユニット（又は空気タンク）内の空間である。空気貯蔵ユニットには、圧縮空気を気体被注入物に送って気体注入する排気口が形成されている。従来のシリンダと空気貯蔵ユニットとの間には、排気孔が１つのみ設けられ、この排気孔の開閉がバルブ機構により制御され、バルブ機構は、弁体及びばねから構成される。ピストン本体が発生させる圧縮空気により弁体を押動するとばねが圧縮され、圧縮空気が空気貯蔵ユニットの空気貯蔵チャンバ内に進入し、空気貯蔵チャンバ内に貯蔵された圧縮空気は、弁体に背向圧を発生させ、ポンピング段階で背向圧が弁体の開きを抑制し、相対的にピストン本体が動作するときに発生する圧縮空気が弁体を押動する際、抵抗力が発生して円滑に動作しなくなり、このようなピストン本体が動作するときには、さらに大きな抵抗力が発生するため、気体注入速度が下がり、空気圧縮機のモータが過熱してモータの運転効率が低下し、最悪の場合、モータが焼損してしまう虞もあった。そのため、従来の空気圧縮機のシリンダ構造の欠点を改善する技術が求められていた。 The structure of a conventional air compressor basically includes a cylinder. When the piston body reciprocates in the cylinder, compressed air is generated. The generated compressed air pushes the valve mechanism through the exhaust hole of the cylinder, and the compressed air enters another space for storing the compressed air. This space is, for example, the space inside the air storage unit (or air tank). The air storage unit is formed with an exhaust port for sending compressed air to a gas object to be injected for gas injection. Only one exhaust hole is provided between the conventional cylinder and the air storage unit, the opening and closing of the exhaust hole is controlled by a valve mechanism, and the valve mechanism is composed of a valve body and a spring. When the valve body is pushed by the compressed air generated by the piston body, the spring is compressed, the compressed air enters the air storage chamber of the air storage unit, and the compressed air stored in the air storage chamber is backed by the valve body. A counter pressure is generated, the back pressure suppresses the opening of the valve body at the pumping stage, and when the compressed air generated when the piston body operates relatively pushes the valve body, a resistance force is generated. When it does not operate smoothly and such a piston body operates, a larger resistance force is generated, so that the gas injection speed decreases, the motor of the air compressor overheats, and the operating efficiency of the motor decreases, which is the worst. In that case, there is a risk that the motor will burn out. Therefore, there has been a demand for a technique for improving the defects of the cylinder structure of the conventional air compressor.

本発明の課題は、空気圧縮機のシリンダ上に排気ベースを設け、ピストン本体を動作させるシリンダと排気ベースとが一体形成で製造され、シリンダが結合されたメインフレームにモータが固定される空気圧縮機のシリンダ排気構造を提供することにある。
本発明のもう一つの課題は、空気圧縮機のシリンダ上に排気ベースを設け、排気ベースの外筒壁に複数の排気孔が形成され、排気ベースの外筒壁には、弾性薄膜が嵌設され、空気圧縮機により発生された圧縮空気が、複数の排気孔を介して弾性薄膜を押動し、空気貯蔵ユニットの空気貯蔵チャンバ内に進入し、弾性薄膜が速やかに閉じる特性を利用し、空気貯蔵ユニットの空気貯蔵チャンバ内に進入する単位時間当たりの圧縮空気量が増大する空気圧縮機のシリンダ排気構造を提供することにある。 An object of the present invention is air compression in which an exhaust base is provided on the cylinder of an air compressor, the cylinder for operating the piston body and the exhaust base are integrally formed, and the motor is fixed to the main frame to which the cylinders are connected. The purpose is to provide a cylinder exhaust structure for the machine.
Another object of the present invention is to provide an exhaust base on the cylinder of an air compressor, to form a plurality of exhaust holes on the outer cylinder wall of the exhaust base, and to fit an elastic thin film on the outer cylinder wall of the exhaust base. The compressed air generated by the air compressor pushes the elastic thin film through the plurality of exhaust holes, enters the air storage chamber of the air storage unit, and utilizes the property that the elastic thin film closes quickly. It is an object of the present invention to provide a cylinder exhaust structure of an air compressor in which the amount of compressed air per unit time entering the air storage chamber of an air storage unit is increased.

As shown in FIGS. 1 to 4, unlike the conventional technique in which only one exhaust hole is formed on the top wall 21 of the cylinder 2 of the cylinder exhaust structure of the air compressor according to the embodiment of the present invention. The exhaust base 3 described above is provided. The exhaust base 3 and the top wall 21 of the cylinder 2 are integrally formed. A plurality of exhaust holes 31 and 32 and at least one annular concave groove 33 are formed in the outer cylinder wall 30 of the exhaust base 3. The plurality of exhaust holes 31, 32 may have the same or different hole diameters. When the hole diameter of the exhaust hole 31 is the hole diameter A and the hole diameter of the exhaust hole 32 is the hole diameter B, the hole diameters A and B may be the same or different (that is, A = B or A> B, or A <B may be used). An elastic thin film 4 is fitted on the outer cylinder wall 30 of the exhaust base 3. At least one annular shoulder 41 that can be engaged with the annular groove 33 of the outer cylinder wall 30 of the exhaust base 3 is provided on the inner surface of one end of the elastic thin film 4, and the elastic thin film 4 is provided on the outer cylinder wall of the exhaust base 3. The exhaust holes 31 and 32 described above may be closed by the other end of the elastic thin film 4 to prevent them from sliding off the 30 (see FIG. 2). The exhaust holes 31 and 32 described above are in an open state or a closed state, and are completely controlled by the elastic thin film 4 fitted in the outer cylinder wall 30 of the exhaust base 3 (see FIGS. 3 and 4). ). Long side plates 23 extending horizontally extending outward are extended on both front and rear sides near the top wall 21 of the cylinder 2. At both left and right ends of the two long side plates 23, two inverted L-shaped fitting clamps 231 extending upward and corresponding to each other are extended, and an accommodation channel is provided between the fitting clamp 231 and the long side plate 23. 232 is formed (see FIGS. 1 and 2). A plurality of manifolds 52, 53, 54, 55 communicating with the air storage unit 5 are provided on the cylindrical air storage unit 5 having an opening 51 and an air storage chamber 50 at one end. A flat side plate 56 having an appropriate thickness spreads around the opening 51 of the air storage unit 5, and an L-shaped docking plate 561 is provided on the two flat side plates 56 facing each other, and the docking plate 561 An accommodating channel 562 is formed between the air storage unit 56 and the flat side plate 56, and when the air storage unit 5 is swiveled, the flat side plate 56 of the air storage unit 5 is quickly inserted into the accommodating channel 232 of the fitting clamp 231. Since the long side plate 23 of the cylinder 2 is housed in the housing channel 562 of the docking plate 561 and the air storage unit 5 is firmly coupled on the cylinder 2, the two members of the air storage unit 5 and the cylinder 2 can be attached and detached. Can be combined.

図２及び図４を参照する。図２及び図４に示すように、ピストン本体１４がシリンダ２内で往復運動し続けて発生された圧縮空気が弾性薄膜４を押動すると、圧縮空気が排気孔３１，３２を通って空気貯蔵ユニット５の空気貯蔵チャンバ５０内に進入する。シリンダ２のピストン本体１４の動作の開始から終了までの期間、ポンピングの初期段階で発生した圧縮空気が、排気孔３１，３２から空気貯蔵チャンバ５０内に速やかに進入し、弾性薄膜４を利用して速やかに閉じる特性を利用し、空気貯蔵ユニット５の空気貯蔵チャンバ５０に進入する単位時間当たりの圧縮空気量が増大する。ポンピングの中後期段階では、既に大量の圧縮空気が空気貯蔵チャンバ５０内に進入されているため、空気貯蔵チャンバ５０内の圧縮空気が弾性薄膜４に対して反作用力を発生させる。本明細書中で背向圧は、弾性薄膜４の開きを抑制するが、これはピストン本体１４が押圧する圧縮空気の抵抗力がさらに大きくなることを意味する。本発明では、異なる孔径の排気孔３１，３２及び弾性薄膜４を組み合わせ、空気貯蔵チャンバ５０内の背向圧により弾性薄膜４が受圧状態となるが、異なる孔径の排気孔３１，３２を閉止する弾性薄膜４の背向圧がそれぞれ異なるため、圧縮された空気が小さめの背向圧の弾性薄膜４を優先的に押動し、シリンダ２内に発生し続ける圧縮空気が空気貯蔵チャンバ５０内に進入し易いため、全体的にピストン本体１４が円滑に動作してポンピング効率が高まり、容易に気体注入の速度を高めることができる。 See FIGS. 2 and 4. As shown in FIGS. 2 and 4, when the compressed air generated by the piston body 14 continuously reciprocating in the cylinder 2 pushes the elastic thin film 4, the compressed air is stored in the air through the exhaust holes 31 and 32. Enter the air storage chamber 50 of the unit 5. During the period from the start to the end of the operation of the piston body 14 of the cylinder 2, the compressed air generated in the initial stage of pumping quickly enters the air storage chamber 50 from the exhaust holes 31 and 32, and utilizes the elastic thin film 4. The amount of compressed air per unit time that enters the air storage chamber 50 of the air storage unit 5 is increased by utilizing the property of quickly closing. In the middle and late stages of pumping, since a large amount of compressed air has already entered the air storage chamber 50, the compressed air in the air storage chamber 50 generates a reaction force against the elastic thin film 4. In the present specification, the back pressure suppresses the opening of the elastic thin film 4, which means that the resistance force of the compressed air pressed by the piston body 14 is further increased. In the present invention, the exhaust holes 31 and 32 having different pore diameters and the elastic thin film 4 are combined, and the elastic thin film 4 is put into a pressure receiving state due to the back pressure in the air storage chamber 50, but the exhaust holes 31 and 32 having different pore diameters are closed. Since the back pressures of the elastic thin films 4 are different from each other, the compressed air preferentially pushes the elastic thin films 4 having a smaller back pressure, and the compressed air that continues to be generated in the cylinder 2 enters the air storage chamber 50. Since it is easy to enter, the piston body 14 operates smoothly as a whole, the pumping efficiency is increased, and the speed of gas injection can be easily increased.

図５及び図６に示すように、本発明の他の実施形態に係る空気圧縮機のシリンダ排気構造は、排気ベース３の頂端面に少なくとも１つの窪み部３４が設けられ、排気ベース３内の圧力貯蔵空間３５が小さくなり、圧縮された空気が速やかに排気孔３１，３２を通って空気貯蔵チャンバ５０内に進入する。 As shown in FIGS. 5 and 6, in the cylinder exhaust structure of the air compressor according to another embodiment of the present invention, at least one recess 34 is provided on the top end surface of the exhaust base 3, and the inside of the exhaust base 3 is provided. The pressure storage space 35 becomes smaller, and the compressed air quickly enters the air storage chamber 50 through the exhaust holes 31 and 32.

また、本実施形態は、少なくとも１つの窪み部３４を利用して圧力貯蔵空間３５を変化させて圧縮比を変更し、合理的に制御した高圧圧力値を得る。 Further, in the present embodiment, the pressure storage space 35 is changed by utilizing at least one recess 34 to change the compression ratio, and a reasonably controlled high pressure value is obtained.

上述したことから分かるように、従来、空気圧縮機のシリンダ２と空気貯蔵ユニット５との間の中間壁上に排気孔が１つのみ設けられていた従来技術を飛躍的に改善するために、本発明では、シリンダ２上に排気ベース３が設けられる。排気ベース３の外筒壁３０は、複数の排気孔３１，３２を有し、排気ベース３の外筒壁３０には、弾性薄膜４が嵌設され、空気圧縮機により発生された圧縮空気が、複数の排気孔３１，３２を通って弾性薄膜４を押動し、空気貯蔵ユニット５の空気貯蔵チャンバ５０内に進入し、弾性薄膜４が速やかに閉じる特性を利用し、空気貯蔵ユニット５の空気貯蔵チャンバ５０内に進入する単位時間当たりの圧縮空気量を増大させ、圧縮された空気が排気孔３１，３２を速やかに通って空気貯蔵チャンバ５０内に進入し、ピストン本体１４が円滑に動作してポンピング効率を高めることができるため、本発明は進歩性を備えて実用的である。 As can be seen from the above, in order to dramatically improve the conventional technique in which only one exhaust hole is conventionally provided on the intermediate wall between the cylinder 2 of the air compressor and the air storage unit 5. In the present invention, the exhaust base 3 is provided on the cylinder 2. The outer cylinder wall 30 of the exhaust base 3 has a plurality of exhaust holes 31 and 32, and the elastic thin film 4 is fitted in the outer cylinder wall 30 of the exhaust base 3, and the compressed air generated by the air compressor is discharged. , Pushing the elastic thin film 4 through the plurality of exhaust holes 31 and 32, entering the air storage chamber 50 of the air storage unit 5, and utilizing the property that the elastic thin film 4 quickly closes, the air storage unit 5 The amount of compressed air per unit time that enters the air storage chamber 50 is increased, and the compressed air quickly passes through the exhaust holes 31 and 32 and enters the air storage chamber 50, so that the piston body 14 operates smoothly. The present invention is progressive and practical because the pumping efficiency can be increased.
